Cupric stearate CAS 660-60-6 CuSt₂

Produced by complex reaction of an ethanol solution of copper acetate with an acetic acid solution of stearic acid. Preparation Mix an equimolar amount of ethanolic solution of copper acetate with an ethanolic solution of stearic acid, the resulting precipitate is washed with ethanol to remove the free acid, and the resulting product can be recrystallized with dialkane. The product can be dried under vacuum at 100°C in the presence of phosphorus pentoxide to obtain a light blue powdery product.
